Moreover, not all of the configurations described in each embodiment are essential constituent requirements of the present invention.

1. 1. Method of the present embodiment First, the method of the embodiment of the motion monitoring system as an example of the system according to the present invention will be described. In the following, as the exercise monitoring device (detection device) used in the exercise monitoring system, for example, a wearable device (wrist device) equipped with a pulse wave sensor or a body motion sensor worn on the wrist of a user will be described as an example.

The wearable device as an exercise monitoring device used in an exercise monitoring system is equipped with a pulse wave sensor that acquires pulse wave information as the user's biological information and a body motion sensor that acquires the user's motion information (body motion information). ing. Furthermore, the wearable device is GPS (Global Positioning System) as an example of a positioning system using a position information satellite called a Global Navigation Satellite System (GNSS) that acquires the user's position information. Is provided. The wearable device may be a wearable device worn on other parts of the user such as the neck and ankle.

The pulse wave sensor can acquire pulse wave information such as a pulse rate. As the pulse wave sensor, for example, a photoelectric sensor (optical sensor) is used. In this case, a method of detecting the reflected light or the transmitted light of the light radiated to the living body with the photoelectric sensor can be considered. Since the amount of absorbed light and the amount of reflection of the irradiated light in the living body differ depending on the blood flow in the blood vessel, the sensor information detected by the photoelectric sensor becomes a signal corresponding to the blood flow, etc., and by analyzing the signal, Information about the beat can be obtained. However, the pulse wave sensor is not limited to the photoelectric sensor, and other sensors such as an electrocardiograph and an ultrasonic sensor may be used.

The body motion sensor is a sensor that detects the body motion of the user. As the body motion sensor, an acceleration sensor, an angular velocity sensor, an orientation sensor (geomagnetic sensor), a pressure sensor (altitude sensor), or the like can be considered, but other sensors may be used.

GPS, also called a global positioning system, is a satellite positioning system for measuring the current position on the earth based on a plurality of satellite signals. GPS has a function of acquiring a user's position information by performing positioning calculation using GPS time information and orbit information, and a time adjustment function in a clock function.

2. Exercise monitoring system Next, the configuration of an exercise monitoring system as an example of the system according to the present invention will be described with reference to FIGS. 1, 2, 3, 4, and 5. FIG. 1 is a schematic configuration diagram showing an outline of a motion monitoring system as an example of the system according to the present invention. FIG. 2 is an external view showing a schematic configuration of a wearable device used in a motion monitoring system. FIG. 3 is an external view showing an example of wearing a wearable device. FIG. 4 is a cross-sectional view showing the configuration of the wearable device. FIG. 5 is a block diagram showing a configuration example of the exercise monitoring system.

As shown in FIG. 1, the motion monitoring system 100 according to the present embodiment includes a wearable device 200 as a detection device equipped with a pulse wave sensor as a biological sensor (photoelectric sensor) and GPS, and data communication with the wearable device 200. It includes a portable device 300 as an example of a possible information processing device, and a server 400 as another example of an information processing device connected to the portable device 300 via a network NE.

GPS160 (see FIG. 5) as a global navigation satellite system provided in the wearable device 200 receives radio waves (satellite signals) from GPS satellite 8 to correct the internal time and perform positioning calculation to position the position. It has a function to acquire information.

The GPS satellite 8 is an example of a position information satellite that orbits a predetermined orbit over the earth. The GPS satellite 8 transmits a high-frequency radio wave on which a navigation message is superimposed, for example, a radio wave having a frequency of 1.57542 GHz (L1 wave) to the ground. In the following description, for example, a radio wave of 1.57542 GHz on which a navigation message is superimposed is referred to as a satellite signal. The satellite signal is a circularly polarized wave with right-handed polarized waves.

Currently, there are a plurality of GPS satellites 8 (only four are shown in FIG. 1). In order to identify from which GPS satellite 8 the satellite signal was transmitted, each GPS satellite 8 superimposes a unique pattern of 1023 chips (1 ms period) called a C / A code (Coarse / Acquisition Code) on the satellite signal. The C / A code looks like a random pattern, with each chip being either +1 or -1. Therefore, the C / A code superimposed on the satellite signal can be detected by correlating the satellite signal with the pattern of each C / A code. In this way, it is possible to obtain a satellite number that identifies from which GPS satellite 8 the satellite signal was transmitted.

The GPS satellite 8 is equipped with an atomic clock. The satellite signal contains extremely accurate GPS time information timed by an atomic clock. The control segment on the ground measures a slight time error of the atomic clock mounted on each GPS satellite 8. The satellite signal also contains time correction parameters to correct the time error. The wearable device 200 receives the satellite signal (radio wave) transmitted from one GPS satellite 8, and uses the GPS time information and the time correction parameter, which are the time information of the GPS satellite 8 included in the satellite signal (radio wave), to provide time information. Can be obtained.

The satellite signal also includes orbit information (satellite orbit information) indicating the position of the GPS satellite 8 in orbit and data capable of acquiring a pseudo distance between the GPS satellite 8 and the wearable device 200. The pseudo distance acquired from the satellite signal, the frequency information of the satellite signal, the satellite number, and the satellite time information (time information of the positioning satellite system) are referred to as observation data of GPS satellite 8 (hereinafter, "observation data"). do.

The wearable device 200 can perform positioning calculation using GPS time information and orbit information. The positioning calculation is performed on the premise that the internal time of the wearable device 200 includes a certain error. That is, in addition to the x, y, and z parameters for specifying the three-dimensional position of the wearable device 200, the time error is also unknown. Therefore, the wearable device 200 receives satellite signals (radio waves) transmitted from, for example, three or more GPS satellites 8, and performs positioning calculation using the GPS time information and orbit information contained therein. You can get the location information of your current location.

The mobile device 300 can be composed of, for example, a smartphone or a tablet-type terminal device. The portable device 300 includes a wearable device 200 that uses a pulse wave sensor as a biological sensor that is a photoelectric sensor, and short-range wireless communication or wired communication (not shown) that can exemplify, for example, Bluetooth (registered trademark) communication. Etc. are connected.

The wearable device 200 and the portable device 300 in the present embodiment have a Bluetooth function, and the mobile device 300 and the wearable device 200 are connected by Bluetooth communication. Bluetooth communication can perform wireless communication between Bluetooth-equipped devices in a radius of about 10 to 100 m while dividing the 2.4 GHz band into a plurality of frequency channels and performing frequency hopping that randomly changes the frequency to be used. The wearable device 200 and the portable device 300 can be suitably connected by Bluetooth communication, which is suitable for mobile communication as a simple digital wireless communication with little directivity.

Further, the Bluetooth communication of the present embodiment applies the communication by Bluetooth Low Energy (also referred to as Bluetooth 4.0). Bluetooth Low Energy (hereinafter referred to as BLE) is a standard for short-range wireless communication using radio in the 2.4 GHz band, and power saving is emphasized. In BLE, the host side and the device side communicate with each other with a profile called GATT (Generic ATTribute). By performing such communication to which BLE is applied, it is possible to significantly reduce power consumption as compared with the conventional version, and it is possible to prolong the usable time of the wearable device.

Further, the mobile device 300 can be connected to a server 400 such as a PC (Personal Computer) or a server system via a network NE. As the network NE here, various network NEs such as WAN (Wide Area Network), LAN (Local Area Network), and short-range wireless communication can be used. In this case, the server 400 is realized as a processing storage unit that receives and stores pulse wave information and body movement information measured by the wearable device 200 from the mobile device 300 via the network NE.

The wearable device 200 does not need to be directly connected to the network NE as long as it can communicate with the mobile device 300. Therefore, it is possible to simplify the configuration of the wearable device 200. However, in the motion monitoring system 100, it is possible to omit the portable device 300 and directly connect the wearable device 200 and the server 400. In this case, the wearable device 200 has a function of processing the measurement information included in the mobile device 300, and a function of transmitting the measurement information to the server 400 and receiving the information from the server 400.

Further, the exercise monitoring system 100 is not limited to the one realized by the server 400. For example, the exercise monitoring system 100 may be realized by the portable device 300. For example, a mobile device 300 such as a smartphone often has restrictions on processing performance, storage area, and battery capacity as compared with a server system, but in consideration of recent performance improvements, it is possible to secure sufficient processing performance and the like. It is also possible. Therefore, if the requirements such as processing performance are satisfied, the portable device 300 can be used as the motion monitoring system 100 according to the present embodiment.

Further, the motion monitoring system 100 according to the present embodiment is not limited to the one realized by one device. For example, the motion monitoring system 100 may include two or more of the wearable device 200, the portable device 300, and the server 400. In this case, the process executed by the exercise monitoring system 100 may be executed by any one device, or may be distributed by a plurality of devices. Further, it is not prevented that the exercise monitoring system 100 according to the present embodiment includes a device different from the wearable device 200, the portable device 300, and the server 400.

Further, when the improvement of the terminal performance or the usage mode is taken into consideration, the wearable device 200 can be used as an embodiment for realizing the motion monitoring system 100 according to the present embodiment.

In addition, the processing of each part of the exercise monitoring system 100 according to the present embodiment can be realized by a program. That is, the method of the present embodiment is a method of monitoring the position information of the user during exercise, and includes a step of acquiring an instruction to start measurement of the measurement position information and a step of acquiring an instruction to end the measurement of the measurement position information. , Acquire the observation data of the satellite signal in the first period from the start of measurement to the determination of the first measurement position information (first measurement position information), and the instruction to end the measurement from the determination of the first measurement position information. The step of outputting a plurality of measurement position information in the second period up to, the observation data of the satellite signal, and the plurality of measurement position information are acquired, and the calculated position information corresponding to the first period is obtained based on the observation data. It can be applied to a program that causes a computer to execute a process including a step of determining the above and a step of outputting a plurality of measurement position information together with the calculated position information.

Further, the motion monitoring system 100 of the present embodiment includes a memory for storing information (for example, a program and various data) and a processor that operates based on the information stored in the memory. In the processor, for example, the functions of each part may be realized by individual hardware, or the functions of each part may be realized by integrated hardware. The processor may be, for example, a CPU (Central Processing Unit). However, the processor is not limited to the CPU, and various processors such as GPU (Graphics Processing Unit) and DSP (Digital Signal Processor) can be used. Further, the processor may be a hardware circuit by ASIC. The memory may be, for example, a semiconductor memory such as SRAM (Static Random Access Memory) or DRAM (Dynamic Random Access Memory), a register, or a magnetic storage device such as a hard disk device. However, it may be an optical storage device such as an optical disk device. For example, the memory stores instructions that can be read by a computer, and when the instructions are executed by the processor, the functions of each part of the motion monitoring system 100 are realized. The instruction here may be an instruction that constitutes a program, or may be an instruction that instructs the hardware circuit of the processor to operate.

Mobile device As shown in FIG. 5, the mobile device 300 performs a position calculation process based on the information communication unit 280 that performs communication processing with the wearable device 200 and the measurement information and position information received by the information communication unit 280. It was processed by the control unit (CPU) 230 as the second processing unit, the storage unit 240 that stores the acquired pulse wave information, body movement information, position information, etc. of the user, and the control unit (CPU) 230. It includes a notification unit 290 for notifying information and a communication processing unit 295 for performing communication processing with the outside.

However, the portable device 300 is not limited to the configuration shown in FIG. 5, and various modifications such as omitting some of these components or adding other components can be performed. For example, the optical sensor unit 40, the body motion sensor unit 170, the GPS 160, etc. included in the wearable device 200 may be included. Further, the portable device 300 may include a measurement information processing unit (not shown) that acquires the user's pulse wave information and body movement information detected by the optical sensor unit 40 and the body movement sensor unit 170 included in the wearable device 200. good.

The information communication unit 280 receives observation data, measurement information or position information (measurement position information) detected and measured by the wearable device 200 and transmitted from the communication unit 80 of the wearable device 200. Further, the information communication unit 280 transmits the calculated position information calculated and processed by the mobile device 300 to the wearable device 200.

The control unit (CPU) 230 as the second processing unit performs various signal processing and control processing using, for example, the storage unit 240 as a work area, and is realized by, for example, a processor such as a CPU or a logic circuit such as an ASIC. can. The control unit (CPU) 230 includes a measurement position information acquisition unit 233, a calculation position information determination unit 235, an output unit 237, and a notification control unit 239. The control unit (CPU) 230 is used by the user during the period from the start of measurement to the end of measurement of the wearable device 200 instructed by the user, and from the start of measurement to the start of positioning of GPS 160 (first period). The position is estimated retroactively from the observation data of the GPS 160 to be used as a plurality of calculated position information, and the positioning of the GPS 160 is started, and the measurement position information in the second period from the determination of the measurement position information by the first positioning to the end of the measurement is performed. At the same time, an instruction is given to store the data in the storage unit 240 or transmit the data to the wearable device 200 or the server 400. Further, the control unit (CPU) 230 performs a process for notifying the notification unit 290 of the measurement information and the position information from the wearable device 200, the calculated calculated position information, and the like.

The measurement position information acquisition unit 233 is the measurement position information and time information in the second period calculated by the GPS 160 provided in the wearable device 200, or the direction sensor 56 and the pressure sensor 57 provided in the wearable device 200.

The measurement position information acquisition unit 233 can store the generated current position information and movement locus information in the storage unit 240, or can use the notification control unit 239 as notification data.

The calculated position information determination unit 235 determines the calculated position information calculated as position information in place of the user's measurement position information corresponding to the first period based on the observation data in the first period transmitted from the wearable device 200. do. It is preferable that the calculated position information determination unit 235 determines the calculated position information with the first measurement position information (first measurement position information) as the initial position. As a result, the position information (position) can be calculated retroactively before the first measurement position information. In addition, since the position at the time of movement due to the user's movement is calculated using the first measurement position information (first measurement position information) as the initial position, it is possible to set an accurate initial position. It is possible to shorten the time required for positioning and improve the accuracy.

The calculated position information determination unit 235 stores the determined calculated position information as log information for each elapsed time in the storage unit 240 together with the current position information and the movement locus information generated by the measurement position information acquisition unit 233, or a notification control unit. It can be used as broadcast data by 239.

The calculation position information determination unit 235 performs positioning calculation on the observation data received from the wearable device 200. In order to do so, the time must be resolved first, and if even one or more position information can be obtained (positioning is possible), the relationship between the measurement time included in the position information and the satellite time information , The measurement time included in the received observation data may be converted into satellite time information to obtain the time. If the positioning has never been successful, the initial time of the mobile device 300 is used. At this time, since the time of the portable device 300 is not always correct, the correction is performed using the time data measured by the wearable device 200 transmitted from the wearable device 200. However, 5 or more satellite data are required in the observation data. After acquiring the time in this way, the GPS assist information of the corresponding time zone is downloaded from the server 400, the Internet, the wearable device 200, or the like. Then, the positioning calculation is performed from the acquired GPS assist information and the observation data to determine the calculated position information.

If the initial position is required, the position information when the wearable device 200 was used last time may be referred to from the history of the server 400 and used. Further, the position information at the time of the first successful positioning or a similar one (the average of several seconds thereafter, the overall average, etc.) may be used for the positioning calculation of the observation data as the initial position. Further, when it is assumed that the distance between the wearable device 200 and the server 400 is close to some extent, the position information of the server 400 may be used as the initial position.

Further, after the calculated position information determination unit 235 determines the calculated position information in the first period, the observation data corresponding to each calculated position information used when calculating the calculated position information is stored in the storage unit 180. It may be deleted from.

The output unit 237 wears the calculated position information in the first period determined by the calculated position information determination unit 235 and the measurement position information and the movement locus information acquired by the measurement position information acquisition unit 233 in the second period. Output to 200 or server 400.

The notification control unit 239 is generated from the user's position information in the second period acquired by the measurement position information acquisition unit 233, the user's calculated position information in the first period determined by the calculation position information determination unit 235, and the like. Based on the user's current position information, movement locus information, user activity information, and the like, control processing such as generation of notification data for each notification and notification instruction to the notification unit 290 is performed. Then, the notification control unit 239 transmits the controlled notification signal to the notification unit (not shown) provided in the device on the network NE via the notification unit 290 or the communication processing unit 295.

The storage unit 240 is generated from the user's position information in the second period acquired by the measurement position information acquisition unit 233, the user's calculated position information in the first period determined by the calculation position information determination unit 235, and the like. Stores the user's current position information, movement trajectory information, or user activity information. Further, the storage unit 240 stores a program for causing the computer to execute a series of processes of the exercise monitoring system 100 according to the present embodiment. The memory can be composed of, for example, a semiconductor memory such as SRAM (Static Random Access Memory) or DRAM (Dynamic Random Access Memory), a magnetic storage device such as a hard disk device, or an optical storage device such as an optical disk device.

The notification unit 290 notifies the user of various information under the control of the notification control unit 239. The notification unit 290 includes a display unit 291 that displays an image, for example, by a liquid crystal display. The notification unit 290 displays an image of activity information such as current position information, movement locus information, or body movement information on the display unit 291 based on, for example, a data signal from the notification control unit 239. As another notification method, the notification unit 290 may include a vibration unit 292 using a vibration motor (vibrator) or the like, or a light emitting body (not shown) for notification using an LED or the like. The vibrating unit 292 notifies the user of various information depending on the strength and length of the vibration of the vibration motor (vibrator), and the light emitting body for notification, such as lighting and blinking of the light emitting body. In addition, these information may be performed only by displaying an image, or may be notified in combination with at least one of vibration and light emission for notification.

The communication processing unit 295 performs communication processing for transmitting the notification signal controlled by the notification control unit 239 to the notification function unit provided in another terminal device or the like. In this case, wireless communication processing according to a short-range wireless communication standard such as Bluetooth can be performed without using a mobile phone network or a wireless LAN network NE.

FIG. 10 is a timing chart showing the acquisition of position information at the start of measurement. FIG. 11 is a flowchart showing a procedure for acquiring position information (log information) at the start of measurement. FIG. 12 is a flowchart showing an example of a procedure for determining calculated position information based on observation data. FIG. 13 is a flowchart showing an example of a procedure for acquiring position information using a barometric pressure sensor. In the following description, the same reference numerals as the above-described configuration of the motion monitoring system will be used.

3.1. Data transmitted / received by the exercise monitoring system First, with reference to FIGS. 6A, 6B, 7 and 8 regarding the data transmitted / received by the exercise monitoring system 100 and the exchange of data between the devices constituting the exercise monitoring system 100. I will explain.

The exercise monitoring system 100 updates the mobile device 300 as log information after acquiring data such as position information measured by the wearable device 200 or at any time during the acquisition of the data. In the mobile device 300, the acquired information is updated to the server 400 as it is and saved as log information. When the wearable device 200 acquires the assist data of the GPS 160, the portable device 300 acquires the assist information (Eph information, etc.) at the time when the operation unit 130 of the wearable device 200 is operated from the server 400, and the wearable device 200. Send to 200. In addition, the mobile device 300 can refer to or transmit the user's past history, reference event, etc. stored in the server 400 as needed. Further, when the position information and the movement locus information of the GPS 160 are transmitted from the wearable device 200 to the mobile device 300 after the measurement is completed, the data configuration (log information configuration) as shown in FIG. 6A is transmitted from the wearable device 200. May be good.

In the wearable device 200 that calculates the position of the user, it takes time to receive the satellite signal from the GPS satellite 8 and start the positioning at the start of the measurement. However, as shown in FIG. 6A, the satellite signal from the GPS satellite 8 is received as observation data (measurement data: hereinafter abbreviated as “meas data”) even before the positioning calculation starts. Then, in addition to the conventional position information (corresponding to the measurement position information), observation data (meas data) or sensor data is added to the log information updated from the wearable device 200 to the portable device 300. The observation data (mes data) of the satellite signal includes the pseudo distance acquired from the satellite signal, the frequency information of the satellite signal, the satellite number, and the satellite time information.

Here, in FIG. 6A, the state of the log information for each elapsed time from the start of measurement is shown. Then, the wearable device 200 outputs observation data (meas data) and measurement position information. In the example shown in FIG. 6A, positioning starts at 37,000 msec (37 seconds) from the start of measurement as the time when the first positioning is successful, and a plurality of log information for the period after this point (second period described later). The measurement position information is determined and output. Here, the measurement position information at the start of positioning is used as the first measurement position information. In the meantime (1000 to 36000 msec), observation data (described as maas data in FIG. 6A), which is information included in the satellite signal from the GPS satellite 8, is acquired and output. Even after 37,000 msec, when positioning is performed and determined as measurement position information, the observation data (mes data) is acquired as log information.

In this motion monitoring system 100, at the start of measurement, until the satellite signal from the GPS satellite 8 is received and positioning is started (until the time when the first positioning is successful, in other words, the first measurement position). The position information (until the information is determined) is determined and referred to as the calculated position information based on the observation data (meas data), thereby shortening the waiting time of the user. FIG. 6B shows an example in which the calculated position information is determined as log information between 1000 msec and 36000 msec from the start of measurement to 37000 msec (37 seconds). In the portable device 300, the log information (data) received from the wearable device 200 is updated as the calculated position information obtained by calculating the position information in the time zone when there is no measurement position information (first period described later). .. By this process, the log information is converted as shown in FIG. 6B.

As a result, the position information before the positioning start time (37,000 msec) (before 36000 msec), which was unknown at the measurement start time of the wearable device 200, is updated on the log of the mobile device 300 as the calculated position information, and it is as if the measurement starts. It is possible to acquire log information as if the positioning was successful from the measurement start time (1000 msec) when the instruction was given.

For example, as shown in FIG. 7, when the calculated position information in the mobile device 300 cannot be determined due to lack of information only at 2000 msec from the start of measurement, the log (log information) at that time is skipped (for example). In FIG. 7, it may be left blank).

Further, when the wearable device 200 and the server 400 can directly communicate with each other without going through the portable device 300, that is, when the wearable device 200 and the server 400 can directly communicate with each other, the above-mentioned exchange can be performed by the direct communication between the wearable device 200 and the server 400. In this case, in the example in which the mobile device 300 exists, the data conversion performed by the mobile device 300 will be performed by the server 400 or the wearable device 200. Specifically, the server 400 first performs post-processing positioning on the log information received from the wearable device 200, and replaces either or both of the observation data (meas data) and the sensor data with the calculated position information. .. Then, the log information of only the converted calculated position information is saved and used for presenting the position information to the user. When performing these processes with the wearable device 200, the observation data (meas data) acquired without the assist information (Eph information, etc.) is saved as past information, and the assist information (Eph information) is later saved. It is a method of acquiring the calculated position information by performing positioning calculation on the past observation data (meas data) when the information etc. can be acquired.

When the position information and the movement locus of the GPS 160 are used after the measurement is completed, the wearable device 200 may transmit the data structure (log information structure) as shown in FIG. Specifically, the information contained in the satellite signal from the GPS satellite 8 until the first positioning is successful, in other words, until the first measurement position information is determined (1000 to 36000 msec). Observation data (described as measurement data in FIG. 8) has been acquired and output. Then, from the time when the first positioning is successful and the first measurement position information is determined at 37,000 msec to the end of the measurement, the observation data (meas data) can be output in addition to the measurement position information. .. With such a configuration, the calculated position information can be determined by the server 400 or the portable device 300 even during the period when the measured position information can be determined, and the measured position information and the calculated position information are compared. Therefore, more accurate position information can be selected as the final position information corresponding to the time.

The data structure (log information structure) when the position information and the movement locus of the GPS 160 are used after the measurement is completed, which was explained with reference to FIG. 8 in the previous stage, can be modified as follows. ..

A modified example of the data configuration (configuration of log information) described with reference to FIG. 8 is until the first positioning is successful, in other words, until the first measurement position information is determined (1000 msec ~). 36000 msec) stores the observation data (Meas data), and after 37000 msec when the first positioning is successful and the first measurement position information is determined, the measurement position information and the observation data (Meas data) are stored at the time. Save as log information (log data) in association with. When the log information (log data) is transmitted to the mobile device 300 or the server 400, the observation data (Meas data) is transmitted at a time of 1000 msec to 36000 msec. Then, among the measurement position information acquired after the time of 37,000 msec, the measurement position information in which the error information of the measurement position information satisfies a predetermined condition may be selected and transmitted. In this case, the predetermined condition is not less than or equal to the threshold value for error information. On the other hand, for the measurement position information that does not satisfy the predetermined condition, the observation data (Meas data) corresponding to the time when the measurement position information is acquired may be transmitted.

3.2. Sending and receiving data in the exercise monitoring system Next, refer to FIGS. 9 and 10 for the timing (sequence) of exchanging data (observation data (mes data), position information, etc.) between the devices constituting the exercise monitoring system 100. I will explain.

The communication timings of the wearable device 200, the portable device 300, and the server 400 constituting the motion monitoring system 100 are as shown in FIG. The communication timing here is started by the user instructing the wearable device 200 to start measurement, and the wearable device 200 starts acquiring satellite signals from the GPS satellite 8.

In the first period, which is between the start of measurement and the success of the first positioning, in other words, the period until the first measurement position information is determined, as shown in FIG. 10, the first measurement time The observation data (mes data) in the above is generated, and then the second measurement time, the third measurement time, ..., And the generation of the observation data (mes data) are continued. Then, in the second period between the success of the first positioning and the instruction to end the measurement, the measurement position information is determined as the first positioning position data, and the second measurement time thereafter, The measurement position information is determined as the positioning position data until the instruction to end the measurement is given at the third measurement time. At this time, observation data (meas data) may be generated at the same time.

Further, the wearable device 200 (CPU 90) acquires GPS assist information including orbit information (satellite orbit information) indicating a position on the orbit of the GPS satellite 8 from the satellite signal from the GPS satellite 8.

After the measurement is completed, the wearable device 200 transmits the observation data (meas data) in the first period and the measurement position information in the second period to the portable device 300. In addition, the wearable device 200 transmits GPS assist information to the mobile device 300.

That is, the portable device 300 determines the calculated position information in the first period as the past position information that dates back from the time when the first positioning is successful (the time when the first measurement position information is determined).

In this way, the CPU 90 of the wearable device 200 uses the satellite orbit information (GPS assist information) acquired and transmitted from the satellite signal transmitted by the GPS satellite 8, and the portable device 300 is in the calculated position corresponding to the first period. Determine the information. Therefore, even if the wearable device 200 and the portable device 300 are not connected by the network NE at the start of measurement, the calculated position information can be determined using the satellite orbit information acquired by the wearable device 200 during that time. The location information in the first period can be presented reliably and time-efficiently.

The mobile device 300 transmits the calculated position information in the determined first period and the measurement position information in the second period in which positioning is performed by the wearable device 200 to the server 400. The server 400 updates (saves) the calculated position information and the measured position information transmitted from the mobile device 300.

When the user tries to confirm the movement locus in the exercise, the position information is acquired from the server 400 and downloaded to the wearable device 200. Then, the user can visually confirm the movement history plotted on the map displayed on the display unit 50 of the wearable device 200 as a movement locus, so that it becomes easy to grasp the results of running and walking.

Specifically, when the user wants to confirm the movement locus (position information) in the exercise, the confirmation instruction is given from the operation unit 130 of the wearable device 200 or the like. The wearable device 200 that has received the instruction requests the position information from the portable device 300. Upon receiving the request, the mobile device 300 transmits the calculated position information in the first period and the measurement position information in the second period to the mobile device 300 as the updated position information. The portable device 300 transmits the received calculated position information in the first period and the measured position information in the second period to the wearable device 200.

For example, the user can confirm the movement locus (position information) in the exercise by the notification unit 290 (display unit 291) of the portable device 300.

3.3. Operation Procedure of Exercise Monitoring System Next, an example of the operation procedure of the exercise monitoring system 100 will be described with reference to FIGS. 11 and 12. FIG. 11 is a flowchart showing an example of a procedure for acquiring position information (log information) at the start of measurement. FIG. 12 is a flowchart showing an example of a procedure for determining calculated position information based on observation data. In the following description, the same reference numerals as those of the components of the motion monitoring system 100 described above will be used.

As shown in FIG. 11, the operation procedure of the motion monitoring system 100 according to the embodiment is measured from the step of instructing the start of measurement from the user (step S101) to the step of instructing the end of measurement from the user (step S118). It is executed according to the procedure up to the step (step S120) of outputting the calculated position information and the measurement position information, which is performed based on the end instruction. Hereinafter, the process will be described with reference to the flowchart of FIG.

First, the user operates the operation unit 130 of the wearable device 200, and when starting his / her own exercise, gives an instruction to the wearable device 200 to start measurement by the accompanying motion monitoring (step S101). Upon receiving the instruction to start measurement, the CPU 90 (first processing unit) of the wearable device 200 receives the satellite signal from the GPS satellite 8 until the first positioning described later succeeds (step S108: Yes). (Step S102).

The CPU 90 determines from the received satellite signal whether or not the number of GPS satellites 8 exceeds the required number (whether or not the required number or more) (step S104). Here, when it is determined that the number of satellites is equal to or greater than the required number (step S104: Yes), the received observation data is transmitted to the mobile device 300. The control unit (CPU) 230 of the mobile device 300 stores the transmitted observation data in the storage unit 240 (step S106). The method of storing the observation data in step S106 differs depending on the resource status such as the capacity of the storage unit 240. For example, when resources can be used abundantly, it may be saved unconditionally, or when there are restrictions on the use of resources, storage conditions may be set within a range in which a predetermined calculated position information can be determined. good.

If it is determined in step S104 that the number of satellites is not more than the required number (step S104: No), the observation data up to that point is stored in the storage unit 240 (step S116), and a series of procedures is completed.

Next, the CPU 90 determines whether or not the first positioning was successful (step S108). In addition, "whether or not the first positioning was successful" may be rephrased as "whether or not the first measurement position information was determined". When it is determined that the first positioning is successful (step S108: Yes), the CPU 90 continues the positioning thereafter and determines the positioning result as the measurement position information in the second period (step S110). Then, the CPU 90 transmits the determined measurement position information to the mobile device 300. If it is determined in step S108 that the first positioning is not successful (step S108: No), the observation data up to that point is stored in the storage unit 240 (step S116), and the series of procedures is completed.

After the measurement position information of the second period is transmitted, the control unit (CPU) 230 of the portable device 300 determines whether or not the storage unit 240 has past observation data (step S112), and the past observation. When there is data (step S112: Yes), the calculated position information is determined as the position information of the first period from the past observation data (step S114). Here, the calculation position information may be determined retroactively from the time side at which the positioning is started, or conversely, from the time side at which the acquisition of the observation data is started toward the time side at which the positioning is started. You may.

If there is no past observation data in step S112 (step S112: No), a series of procedures is completed.

Here, the determination of the calculated position information in step S114 can be performed by the procedure as shown in the flowchart of FIG. First, the satellite time information is acquired (step S201). The satellite time information here is information acquired as accurate time information if positioning is possible, and satellite time information already acquired in positioning can be used.

Next, the control unit (CPU) 230 of the portable device 300 determines whether or not the storage unit 240 has past observation data, as in step S112 in the flowchart of FIG. 11 (step S203). If there is past observation data in step S203 (step S203: Yes), the process proceeds to the procedure for determining the calculated position information as the position information of the first period from the past observation data, and there is no past observation data. In the case (step S203: No), a series of steps is completed.

In the procedure for determining the calculated position information, first, the acquisition time (T1) of the satellite orbit information is determined from the satellite orbit information and the satellite time information of all the received GPS satellites 8 (step S205). Next, the position and moving speed of the GPS satellite 8 at the time of acquisition of the determined satellite orbit information (T1) are determined (step S207). Next, positioning calculation is performed based on the satellite orbit information, the position of the GPS satellite 8, and the moving speed, and the calculated position information is determined (step S209). Next, the calculated position information is updated to the storage unit 240 (step S211). Then, the steps S205 to S211 are repeated until the observation data does not exist in the storage unit 240 (step S203: No), and the calculated position information for each observation data is determined. With the above procedure, the calculated position information can be determined.

Next, the control unit (CPU) 230 determines whether or not there is an instruction to end the measurement from the user (step S118), and if there is an instruction to end the measurement (step S118: Yes), in the first period. The measurement position information in the second period is output together with the calculated position information (step S120), and a series of procedures is completed. If there is no instruction to end the measurement (step S118: No), the process returns to step S114 for determining the calculated position information from the past observation data, and the process is continued.

The calculated position information in the first period and the measurement position information in the second period output by the control unit (CPU) 230 are transmitted to the wearable device 200 and displayed on the display unit 50 or displayed on the portable device 300. It can be displayed to the user by displaying it in the unit 291.

According to the operation procedure of the motion monitoring system as described above, the first processing unit observes in the first period from the start of measurement to the determination of the first measurement position information (determination of the first measurement position information). The data and a plurality of measurement position information in the second period from the determination of the first measurement position information to the acquisition of the measurement end instruction are output, and the second processing unit performs the first measurement based on the observation data. The calculated position information as the position information corresponding to the period is determined, and a plurality of measurement position information is output together with the calculated position information. Therefore, even if the wearable device and the information processing device are not connected by the network NE at the start of measurement, the calculated position information can be determined using the observation data acquired by the wearable device during that time. The position information before the measurement (first period) can be determined. In other words, the position information (position) can be calculated by going back before the first measurement position information.

The calculation position information in step S114 can be determined as the calculation position information with improved accuracy by using the barometric pressure sensor 57 provided in the wearable device 200 together. The procedure for determining the calculated position information based on the atmospheric pressure data acquired by the atmospheric pressure sensor 57 will be described with reference to FIG. FIG. 13 is a flowchart showing an example of a procedure for acquiring position information (calculated position information) using the barometric pressure sensor 57.

First, the control unit (CPU) 230 of the portable device 300 determines whether or not the storage unit 240 has past observation data, as in step S112 in the flowchart of FIG. 11 (step S302). If there is past observation data in step S302 (step S302: Yes), the process proceeds to the procedure for determining the calculated position information as the position information of the first period from the past observation data, and there is no past observation data. In the case (step S302: No), a series of steps is completed.

In the procedure for determining the calculated position information of this example, first, the sea level pressure (P0) included in the observation data is acquired (step S304). Next, the acquisition time (T) of the observation data is acquired (step S306). Next, the altitude (h) at the time of acquiring the observation data is calculated based on the barometric pressure data measured by the barometric pressure sensor 57 (step S308).

Next, it is determined whether or not the position information of the observation data acquisition time (T) exists (step S310). In step S310, when the position information of the observation data acquisition time (T) exists (step S310: Yes), whether or not the difference between the altitude of the position information and the calculated altitude (h) is equal to or less than a certain value. Is determined (step S312). In step S312, when the difference between the altitude of the position information and the calculated altitude (h) is equal to or less than a certain value (step S312: Yes), the process returns to the start and the observation data does not exist in the storage unit 240 (step S312). Step S302: No) is repeated from step S304 to step S316 to determine the calculated position information for each observation data.

In step S312, when the difference between the altitude of the position information and the calculated altitude (h) is not less than a certain value (step S312: No), and in step S310, the position information of the observation data acquisition time (T) does not exist. In the case (step S310: No), the altitude (h) is fixed and the 2D positioning calculation is performed (step S314). Next, the information such as longitude and latitude calculated in step S314 is determined as the calculated position information, and the storage unit 240 is updated (step S316). By determining the calculated position information by adding the altitude information obtained from the measurement result of the barometric pressure sensor 57 in this way, the calculated position information can be determined by reducing the number of positioning satellites.

According to the motion monitoring system 100 described above, the portable device 300 as an information processing device uses the observation data in the first period from the start of measurement of the wearable device 200 to the determination of the first measurement position information. The control unit (CPU) 230, which is the processing unit of 2, determines the calculated position information as the position information corresponding to the first period. Therefore, even if the wearable device 200 and the mobile device 300 or the server 400 are not connected by the network NE at the start of measurement, the network is enabled when the user finishes the exercise and network communication becomes possible, or during the exercise. When communication becomes possible, the observation data acquired by the wearable device 200 can be transmitted to the mobile device 300, and the calculation position information of the first period can be retroactively determined using the observation data in the mobile device 300. The position information in the first period can be determined and output. In other words, using the first measurement position information that was successfully positioned by the wearable device 200 by the portable device 300 and the observation data acquired by the wearable device 200 before the positioning of the first measurement position information was successful. , The position information before the time when the positioning of the first measurement position information is successful can be calculated, determined as the calculated position information in the first period, and output.

Further, by using the first measurement position information (first measurement position information) as the initial position, it is possible to set an accurate initial position, so that the time required for positioning can be shortened and the movement due to the user's movement can be performed. The time position (movement trajectory) can be calculated and presented with high accuracy.

The second processing unit 330 sets the position of the user between the start of measurement and the end of measurement instructed by the user, and the position of the user from the start of measurement to the start of positioning of GPS 160 (first period). It is estimated retroactively from the observation data of the above and used as the calculated position information, and the GPS positioning is started and stored in the storage unit 240 together with the measurement position information in the second period from the determination of the measurement position information by the first positioning to the end of the measurement. Give instructions to make it or send it to other information processing equipment.

The measurement position information acquisition unit 233 is based on the measurement position information and time information in the second period calculated by GPS160, or the direction information and altitude information acquired by the direction sensor 56 and the pressure sensor 57, and the user's current position information acquisition unit 233. Generate position information and movement trajectory information. The measurement position information acquisition unit 233 can store the generated current position information and movement locus information in the storage unit 340, or can use it as display data of the display unit 350.

The calculated position information determination unit 235 determines the calculated position information calculated as the position information instead of the user's measurement position information corresponding to the first period based on the observation data in the first period. The calculated position information determination unit 235 stores the determined calculated position information as log information for each elapsed time in the storage unit 340 together with the current position information and the movement locus information generated by the measurement position information acquisition unit 233, or displays the display unit 350. It can be used as the display data of. The calculation position information determination unit 235 performs positioning calculation on the observation data, but since this positioning calculation is the same as that of the above-described embodiment, detailed description thereof will be omitted.

The output unit 237 supplies the calculated position information in the first period determined by the calculated position information determination unit 235 and the measurement position information and the movement locus information acquired by the measurement position information acquisition unit 233 in the second period to the server 400.

According to the wearable device 200a as such a motion monitoring device, the CPU 390 as a processing unit uses the observation data in the first period from the start of measurement to the determination of the first measurement position information in the first period. It is possible to retroactively determine the calculated position information as the position information corresponding to. Therefore, the position information in the first period can be presented in a short time without being affected by the network connection at the start of measurement.

Further, by dividing the measurement position information in the second period and the calculation position information corresponding to the first period into the first processing unit 190 and the second processing unit 330, the measurement position information is determined. The processing speed can be increased and the user's waiting time can be shortened.

3.5. Modification example of data transmission / reception Regarding the transmission / reception of position information, the mobile device 300 acquires satellite orbit information from the server 400, and the mobile device 300 determines the calculated position information using the satellite orbit information acquired from the server 400. can do. This configuration example will be described with reference to FIG. 15 as a modified example of the timing (sequence) of exchanging data (observation data (meas data), position information, etc.) between the devices constituting the motion monitoring system 100.

As the communication timing in the wearable device 200, the portable device 300, and the server 400 constituting the motion monitoring system 100, a modified example shown in FIG. 15 can be used. The communication timing here is started by the user instructing the wearable device 200 to start measurement, and the wearable device 200 starts acquiring satellite signals from the GPS satellite 8.

Similar to the embodiment described with reference to FIGS. 9 and 10, in the first period from the start of measurement to the success of the first positioning, the first positioning is successful from the first measurement time. Observation data (mes data) is generated up to the nth measurement time immediately before. Then, in the second period between the success of the first positioning and the instruction to end the measurement, the measurement position information is determined as the positioning position data at each measurement time. At this time, observation data (meas data) may be generated at the same time. After the measurement is completed, the wearable device 200 transmits the observation data (meas data) in the first period and the measurement position information in the second period to the portable device 300.

The mobile device 300 that has received the observation data (mes data) and the measurement position information requests the server 400 to acquire satellite orbit information (also referred to as GPS assist information). The server 400 acquires satellite orbit information based on the request from the mobile device 300 and transmits it to the mobile device 300.

The mobile device 300 that has acquired the observation data (mes data), the measurement position information, and the satellite orbit information receives the observation data (mes data) in the first period, the measurement position information in the second period, and the satellite orbit information. Based on the above, the positioning calculation is performed retroactively from the first successful positioning, and the calculated position information is determined as the position information in the first period. That is, the portable device 300 determines the calculated position information in the first period as the past position information that dates back from the time when the first positioning is successful.

The mobile device 300 transmits the calculated position information in the determined first period and the measurement position information in the second period in which positioning is performed by the wearable device 200 to the server 400. The server 400 updates (saves) the calculated position information and the measured position information transmitted from the mobile device 300.

When the user tries to confirm the movement locus in the exercise, the position information is acquired from the server 400 and downloaded to the wearable device 200. Then, the user can visually confirm the movement history plotted on the map displayed on the display unit 50 of the wearable device 200 as a movement locus, so that it becomes easy to grasp the results of running and walking.

Specifically, when the user wants to confirm the movement locus (position information) in the exercise, the confirmation instruction is given from the operation unit 130 of the wearable device 200 or the like. The wearable device 200 that has received the instruction requests the position information from the portable device 300. Upon receiving the request, the mobile device 300 transmits the calculated position information in the first period and the measurement position information in the second period to the mobile device 300 as the updated position information. The portable device 300 transmits the received calculated position information in the first period and the measured position information in the second period to the wearable device 200.

The wearable device 200 is displayed by the display unit 50 as movement locus information (position information) related to the user's movement based on the received calculated position information in the first period and the measurement position information in the second period. Then, the user can visually confirm the movement locus information (position information) from the display of the display unit 50 to the end of the measurement from the start of the measurement.

As the processing timing of the positioning calculation described above, a method of gradually performing the calculation position information determination processing in a time zone when the processing is relatively free is applied, and the calculated position information having a relatively large amount of calculation is used. By performing the determination process, it is possible to reduce the possibility of interfering with the normal (real-time) positioning calculation. In addition, by applying the method of performing the calculation position information determination process when the state shifts to the measurement end state and performing the calculation position information determination process with a relatively large amount of calculation, the normal (real-time) determination process is performed. ) It is possible to reduce the risk of interfering with positioning calculation.

Further, the exercise monitoring system 100 updates the portable device 300 as log information after acquiring data such as position information measured by the wearable device 200 or at any time during the acquisition of the data. Then, in the mobile device 300, the acquired information is updated to the server 400 as it is and stored as log information, but it can be stored in a storage form as in the second modification relating to the position information (log information) shown below. ..

Hereinafter, a modified example 2 relating to the storage of position information (log information) will be described with reference to FIG. FIG. 16 is a list showing the modified example 2 relating to the position information (log information) after the conversion process in chronological order. Modification 2 relating to the storage of position information (log information) shows an example in which the measurement position information cannot be determined using GPS signals during the user's exercise.

Here, FIG. 16 shows the state of the log information for each elapsed time from the start of measurement. Then, the wearable device 200 outputs observation data (meas data) and measurement position information. In the example shown in FIG. 16, positioning starts at 20000 msec from the start of measurement as the time when the first positioning is successful, and the first measurement position information is determined. Then, after the first measurement position information is determined, the measurement position information is determined as log information from the start of measurement to 27,000 msec, but from the subsequent start of measurement from 28,000 msec to 3600 msec, GPS signals are used. The measurement position information has not been determined.

During the period from the start of measurement to 190000 msec and from 28000 msec to 3600 msec, which is the period when the measurement position information cannot be determined, the observation data (FIG. 16) which is the information included in the satellite signal from the GPS satellite 8. Then, it is described as measurement data) and is output. After that, at 37,000 msec from the start of measurement, positioning using GPS signals starts again, and thereafter, a plurality of measurement position information is determined. The observation data (meas data) is acquired as log information even while the positioning is performed and the measurement position information is determined.

Further, by using a mobile device equipped with a plurality of processing units (CPUs), normal (real-time) positioning calculation and determination processing of calculation processing information are processed by separate CPUs, so that each processing can be performed. It is possible to reduce the trouble caused by overlapping.

Further, in the above-described embodiment, GPS using the GPS satellite 8 as a position information satellite included in the Global Navigation Satellite System (GNSS) has been described as an example, but this is only an example. Global navigation satellite systems include other systems such as Galileo (EU), GLONASS (Russia), Hokuto (China), and position information satellites that transmit satellite signals such as geostationary satellites such as SBAS and quasi-zenith satellites. Anything is fine. That is, the wearable devices 200 and 200a are any one of date information, time information, position information and speed information obtained by processing radio waves (radio signals) from position information satellites including satellites other than GPS satellite 8. May be configured to acquire. The global navigation satellite system can be a regional navigation satellite system (RNSS).
